As someone who went to sleep and woke up to the rumble coming from Wilmore Road. This is good news should help to protect jobs. Call me sad, but I’m always happier flying on planes powered by Rolls Royce engines.

Having seen my share of closed British factories (ex: the Raleigh Nottingham bicycle works), I agree. But these new jobs will likely require worker re-training.
Also, the oil will be sourced from various developing countries. Hmm…
“The Jatropha oil was produced from seeds grown on environmentally sustainable farms in Malawi, Mozambique, Tanzania and India.”

I take your point about the Raleigh Nottingham bicycle works they closed because they were making low tech products. The profit margins were too thin to support expensive western jobs. Ideally, jet engines are a bit trickier to make than bikes and the industry should be inherently more profitable. By keeping on top of developements like biofuels firms like Rolls Royse will be able to retain some of their competitive strength.
